After Atisha, the Kadampa lineage was passed down through a succession of great Kadampa Teachers including Dromtönpa, Geshe Potowa, Geshe Sharawa, and Geshe Chekhawa. These precious Teachers were not only great scholars but also spiritual practitioners of immense purity and sincerity. They placed particular emphasis on the practice of Training the Mind (Lojong) by which all our daily life experiences, and especially all our problems, suffering, and difficulties, can be transformed into the spiritual path.
The Kadampa lineage passed from generation to generation until the fourteenth century when it reached the great Buddhist Master Je Tsongkhapa. Je Tsongkhapa clarified all the teachings of Kadam Dharma and made them very accessible to the people of that time. In particular, he showed how to combine Lamrim, and Lojong with Mahamudra Tantra in a unified daily practice. Just as the union of study and practice was a hallmark of the early Kadampas, so the union of Sutra and Tantra was to become a hallmark of the New Kadampas, as the followers of Je Tsongkhapa became known.
